Mattison value and expected return

12 tm, Full PPR

My RBs are Austin Ekeler, Darrell Henderson Jr., James Robinson, Alexander Mattison, and Damien Williams.

The Dalvin Cook owner is 2-2, and his other RBs are Nick Chubb, Damien Harris, and Sony Michel.

My thought was to try and offer Mattison for Damien Harris, emphasizing that he would be locking up the Vike’s backfield for the rest of the season, no matter what happens with Cook.

Is this reasonable?

Yeah that is reasonable
